What is L-Carnitine?

L-Carnitine is an amino acid that occurs naturally within the body. It can be produced out of the amino acids Lysine and Methionine. It is also found in a lot of our high-quality meat sources as well. Quick fun fact: the word carnitine is derived from the Latin word for meat.

L-Carnitine has many proposed benefits, however the most common one is that people show interest in is for fat loss and cognitive function. L-Carnitine aids in fat metabolism by being the main contributor — along with water — that is responsible for freeing up brown fatty acids and transporting them through the mitochondrial wall. Once they pass through the mitochondria, they are then readily available to be used for energy production. This process is called Lipolysis.

When it comes to L-Carnitine being beneficial for cognitive function, it seems as though Acetyl L-Carnitine specifically is best. This is where they attach an Acetyl enzyme to the L-Carnitine. Acetyl L-Carnitine has been shown to cross the blood brain barrier much better than L-Carnitine. It has also been shown to be more easily absorbed by the gut as well. If you only had a choice of one L-Carnitine to use, we would personally recommend Acetyl L-Carnitine, as it is the most well-rounded form.

The recommended dosage for Acetyl L-Carnitine is anywhere between 2000mg – 10,000mg per day. The best dose will vary from person to person and change based on what your own specific goals are. As a general guide I would recommend using 6000mg per day. You can split this dosage up as well, by having 3000mg in the morning, and another 3000mg in the afternoon.

FAQs on L-Carnitine:

What is the best form of L-Carnitine to use?

L-Carnitine comes in many forms including D-Carnitine, Acetyl L-Carnitine, Propionyl L-Carnitine, and L-Carnitine L-Tartrate. The best overall form of L-Carnitine is most definitely Acetyl L-Carnitine. It is undeniably the best when it comes to absorption through the gut and crossing the blood brain barrier. This will allow for greater fat metabolising effects and enhanced cognitive function.

Is L-Carnitine an Amino Acid?
L-Carnitine is a branched non-essential amino acid. This means that it is produced by the body naturally, but it requires the use of two essential amino acids to do so — namely Lysine and Methionine.

How much L-Carnitine should I take?

This will vary from person to person, but the normal recommended dosage of L-Carnitine is anywhere between 1000mg – 3000mg. We believe that you can safely take up to 10,000mg of L-Carnitine per day. We generally recommend 6000mg per day, split up into 2 doses of 3000mg per day. The highest dosage that we recommend is 10,000mg per day, split up into 2 doses of 5000mg per day.

What are the side effects of L-Carnitine?
L-Carnitine can have some potential side effects when you either take too much of it, or during the first couple of days of use. These side effects can include nausea, upset or irritated stomach, and may also cause a mild laxative effect. If you persist with L-Carnitine through the first few dosages, all these side effects will more than likely subside.
